[Javascript] Single vs. Double quotes in Javascript

[Peter-Paul Koch]

>I did not test this code to confirm or deny the 15% faster claim

I did, and cannot confirm it. It seems that single quotes are *sometimes* 
faster in Explorer Windows (roughly 1/3 of my tests did show a faster 
response time), but if Mozilla shows a difference at all, it handles double 
quotes slightly faster. I found no difference at all in Opera.

I cannot say that these experiments confirm the 15% claim.
